I am trying to use module_rewrite to solve your problem, but not success
yet. I am newbie to apache too.

Maybe following will give you some hints

#try to response http://AAA.example.com/test.htm with /AAA/test.htm
RewriteEngine on
RewriteCond %{HTTP_HOST} ^(.*)\.example\.com$
RewriteRule ^/(.*)$ /$1/$2
